Problem copying elements from one modeler to another (edited with code and screencaps)

I have 2 modelers, modelerA and modelerB. I have a list of IDs that only exist in modelerB’s elementRegistry. I want to copy these elements to modelerA

I have an array resB that contains all the ids I want to copy to modelerA.

I’m doing this:

resB.forEach(function (element) {
            el = elementRegistryB.get(element);
            if (el.type === 'bpmn:SequenceFlow') {
                modeling.createConnection(el.source,, {
                    type: 'bpmn:SequenceFlow',
                    waypoints: el.waypoints,
                    businessObject: el.businessObject
                }, el.parent);
            try {
                modeling.createShape(el, {
                    type: el.type,
                    x: el.x,
                    y: el.y,
                    width: el.width,
                    height: el.height,
                    businessObject: el.businessObject
                }, el.parent);
            } catch (e) {

elementRegistryB is the registry of modelerB, where I’m copying from.
modeling refers to modelerA, the target modeler I’m copying elements to.

I’m using these two graphs:

So I want to add the right hand side element called “Asignación de Suministros” and its connections.

What I get is this:

and, if I manually move Asignacion de Suministros, this:

Any help is much appreciated.
